The largest seed in the world is the coco de mer, [1] [2] the seed of a palm tree. [3] It can reach about 30 centimetres (12 inches) long, and weigh up to 18 kilograms (40 pounds). The coco de mer, which produces a giant, dark brown seed, [4] has been protected by the government of the Seychelles because of its rarity [5] – the tree can grow up to 31 m (102 ft) tall, with leaves measuring 6 m (20 ft) long and 3.6 m (12 ft) wide. Kigelia or "sausage seed" (botanical name Kigelia africana) can produce pods weighing up to 12 kg (26 lb), and 12–20 cm (4+1⁄2–8 in) long, but the pod contains seeds.
Other recorded largest seeds include: [6]

The Arecaceae is a family of perennial, flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem, except for the Hyphaene genus, who has branched palms. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.
The coconut tree is a member of the palm tree family (Arecaceae) and the only living species of the genus Cocos. The term "coconut" can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a nut. The name comes from the old Portuguese word coco, meaning "head" or "skull", after the three indentations on the coconut shell that resemble facial features. They are ubiquitous in coastal tropical regions and are a cultural icon of the tropics.
Lodoicea, commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, Lodoicea maldivica, is endemic to the islands of Praslin and Curieuse in the Seychelles. It has the largest seed in the plant kingdom. It was also formerly found on the small islets of St Pierre, Chauve-Souris, and Ile Ronde, all located near Praslin, but had become extinct there for a time until recently reintroduced.
Mora is a genus of large trees in the subfamily Caesalpinioideae of the legume family Fabaceae,.
Idiospermum is a monotypic genus in the family Calycanthaceae. The sole included species is Idiospermum australiense − commonly known as idiotfruit, ribbonwood, or dinosaur tree − which is found only in two small areas of the tropical rainforests of northeastern Queensland, Australia. It is a relic of the ancient forests of Gondwana, surviving in very localised refugia for 120 million years, and displaying features that are almost identical to fossil records from that time. As such it provides an important insight into the very early evolution of flowering plants.
Grias cauliflora, the anchovy pear, is an evergreen fruit tree native to Jamaica, Central America, and Colombia. It is often found near rivers or marshes in large colonies. It belongs to the Lecythidaceae family.
The palm tree Phytelephas aequatorialis, commonly known as Ecuadorian ivory palm, is the main source of Ecuadorean vegetable ivory or tagua, a botanical alternative to ivory. It is found in the tropical rainforests of the western Andean slopes of Ecuador. It has a woody trunk which can grow to 20 m in height and very long pinnate leaves.
Jubaea is a genus of palms with one species, Jubaea chilensis, commonly known in English as the Chilean wine palm or Chile cocopalm, and palma chilena in Spanish. It is native to southwestern South America and is endemic to a small area of central Chile between 32°S and 35°S in southern Coquimbo, Valparaíso, Santiago, O'Higgins, and northern Maule regions.
The Jardin de l'État, formerly known as the Jardin du Roy, is a historic botanical garden on the island of Réunion, found in the capital Saint-Denis.
Attalea is a large genus of palms native to Mexico, the Caribbean, Central and South America. This pinnately-leaved, non-spiny genus includes both small palms lacking an aboveground stem and large trees. The genus has a complicated taxonomic history, and has often been split into four or five genera based on differences in the male flowers. Since the genera can only be distinguished on the basis of their male flowers, the existence of intermediate flower types and the existence of hybrids between different genera has been used as an argument for keeping them all in the same genus. This has been supported by recent molecular phylogenies.
Drift seeds and drift fruits are seeds and fruits adapted for long-distance dispersal by water. Most are produced by tropical trees, and they can be found on distant beaches after drifting thousands of miles through ocean currents. This method of propagation has helped many species of plant such as the coconut colonize and establish themselves on previously barren islands. Consequently, drift seeds and fruits are of interest to scientists who study these currents.
Cariniana is a genus of trees in the family Lecythidaceae, first described as a genus in 1842. The entire genus is native to South America. Many are of importance for timber production. Species of this genus may be known commonly as jequitibá.
Grias haughtii is a species of woody plant in the Monkeypot family Lecythidaceae. It is found only in Colombia in non-flooded lowland forests. Its most remarkable feature is its leaves, which can be up to 5.5 feet in length by 16.5 inches in width. It also produces exceptionally large seeds, up to 2.7 inches (69 mm) in length by one inch (25 mm) in diameter.
Barringtonia asiatica is a species of Barringtonia native to mangrove habitats from islands of the Indian Ocean in the west to tropical Asia and islands of the western Pacific Ocean. It is grown along streets for decorative and shade purposes in some parts of India, for instance in some towns on the southeastern shore. It is also known as Box Fruit due to the distinct box-shaped fruit it produces. The local name futu is the source of the name for the Polynesian island Futuna. The type specimen was collected by botanist Pehr Osbeck on a sandy beach area on the island of Java, later to be described by Carl Linnaeus in his Species Plantarum in 1753.
Ficus insipida is a common tropical tree in the fig genus of the family Moraceae growing in forest habitats along rivers. It ranges from Mexico to northern South America.
Gustavia superba is an understory tree that grows in Central and north-western South America. Common names include membrillo, sachamango and heaven lotus. The trunk is around 5-10m high with the leaves radiating from the top.
The nut and tree of the coco de mer is a rare species of palm tree native to Africa, in the Seychelles archipelago in the Indian Ocean. It is the subject of various legends and lore. Coco de mer is endemic to the Seychelles islands of Praslin and Curieuse. Before the Seychelles were discovered and settled, nuts of this species were sometimes carried by the ocean currents to distant shores, such as those of the Maldives, where the tree was unknown. These floating nuts did not germinate. The exceptional size and suggestive form of the nut, the circumstances of its discovery, and some unusual qualities of the trees have given rise to several legends.
Morus celtidifolia, the Texas mulberry, is a plant species native to South America, Central America, Mexico, and the southwestern United States, ranging from Argentina north as far as Arizona and Oklahoma. In the US, it grows in canyons and on slopes, usually near streams, from 200–2,200 metres in elevation. It is very often referred to as "Morus microphylla," including in Flora of North America, but recent studies suggest that these names are synonymous with M. celtidifolia holding priority.
Scott Alan Mori was a swiss and american botanist and plant collector. He specialized in the systematics and ecology of neotropical Lecythidaceae and Amazonian and Guianian floristics.
The Cartagena Botanical Garden is located in the hills above Cartagena, in Turbaco, Bolívar, Colombia. It stretches over nine hectares, of which three hectares are natural tropical dry forest and six hectares are dedicated to botanical collections.
